본 발명은 타이어용 고무조성물에 관한 것으로, 좀더 상세하게는 발암물질인 니트로소아민(nitrosoamine)을 생성하지 않는 환경친화적인 새로운 타이어용 고무조성물에 관한 것이다.The present invention relates to a rubber composition for a tire, and more particularly, to a new rubber composition for an environment-friendly tire that does not produce nitrosoamine, a carcinogen.
본 발명의 목적은 안정적인 가교시스템을 가지고 있으나 물질의 분자구조내에 2차 아민의 형태를 가지고 있어서 발암물질인 니트로소아민을 형성하여 환경유해요소로 작용하는 기존의 고무조성물을 대체할 수 있는 새로운 고무조성물을 제공함에 있다.It is an object of the present invention to have a stable crosslinking system, but in the form of secondary amines in the molecular structure of the material to form a carcinogen nitrosoamine to replace the existing rubber composition acting as an environmentally harmful element In providing a composition.
본 발명에 의한 타이어용 고무조성물은 분자구조 내에 2차아민 구조를 갖지 않는 물질을 함유하고 있기 때문에, 종래의 고무조성물의 물성과 비교하여 동등한 수준 이상의 물성을 유지하면서도, 특히 고무조성물의 노화물성이 현저하게 개선되면서도 발암물질인 니트로소아민을 생성하지 않는 환경친화적이라는 장점이 있다.Since the rubber composition for tires according to the present invention contains a substance having no secondary amine structure in its molecular structure, the rubber composition of the rubber composition is particularly maintained while maintaining the properties of equivalent or higher properties as compared with those of conventional rubber compositions. Significantly improved, but does not produce a carcinogenic nitrosoamine has the advantage of being environmentally friendly.
Description
본 발명은 타이어용 고무조성물에 관한 것으로, 좀더 상세하게는 발암물질인 니트로소아민(nitrosoamine)을 생성하지 않는 환경친화적인 새로운 타이어용 고무조성물에 관한 것이다.The present invention relates to a rubber composition for a tire, and more particularly, to a new rubber composition for an environment-friendly tire that does not produce nitrosoamine, a carcinogen.
기존의 천연고무가 블렌드된 고무조성물의 가교시스템은 촉진제로서 주로 설펜아미드(sulfenamide)계 촉진제를 사용하여 왔는데, 이들 고무조성물의 가교시스템에서 설펜아미드계를 촉진제로 사용하는 가교시스템은 다른 촉진제에 비해 높은 스코치안정성 등 보다 안정적인 가교형태를 갖는다.Conventional crosslinking systems of natural rubber-blended rubber compositions have mainly used sulfenamide-based accelerators as accelerators. Crosslinking systems using sulfenamide-based accelerators in crosslinking systems of these rubber compositions are It has a more stable crosslinked form such as high scorch stability.
설펜아미드계 촉진제 중에서 MOR(N-oxydiethylene-2-benzothiazylsulfenamid e) 도 다른 촉진제에 비해 높은 스코치안정성을 지니나, 다른 촉진제에 비해 상대적으로 모듈러스(modulus)가 하락하는 단점을 지니고 있기 때문에, 이러한 문제점을 보완하기 위하여 가교제로 4,4-디티오디모폴린(4,4-dithiodimorpholine ; 이하 Sulfasan-R)과 같이 모노설파이드(mono-sulfide) 또는 디설파이드(di-sulfide) 결합을 형성하게 되어 폴리설파이드(poly-sulfide) 형태의 결합보다 노화시에 물성하락률이 작은 장점을 지닌 황공여 형태(sulfur donor type)의 가류제를 첨가하게 된다.MOR (N-oxydiethylene-2-benzothiazylsulfenamid e) among sulfenamide-based accelerators has higher scorch stability than other accelerators, but has a disadvantage in that modulus decreases compared to other accelerators. In order to form a polysulfide (mono-sulfide) or a disulfide (di-sulfide) bond such as 4,4-dithiodimorpholine (hereinafter referred to as Sulfasan-R) as a crosslinking agent, Sulfur donor type vulcanizing agent is added, which has the advantage of lower property degradation rate at aging than sulfide type binding.
그러나, 이들 두 물질을 사용하는 가교시스템은 안정적인 가교결합을 이루기는 하나, 물질내에 2차아민 형태의 작용기를 포함하고 있어서 발암물질인 니트로소아민을 발생시키는 문제점 즉,설펜아미드를 촉진제로 사용하는 가교시스템 중에서 사용하는 촉진제나 가류제가 분자구조 내에 2차아민의 형태를 갖는 재료는 공기중의 질소산화물들과 반응하여 발암물질인 니트로소아민을 형성하게 되는 문제점을 안고 있다.However, a crosslinking system using these two materials achieves stable crosslinking, but contains a functional group in the form of a secondary amine in the material, thereby causing a problem of generating carcinogen nitrosoamine, that is, using sulfenamide as an accelerator. Materials having the form of secondary amines in the molecular structure of accelerators or vulcanizing agents used in crosslinking systems have the problem of reacting with nitrogen oxides in air to form nitrosoamines, which are carcinogens.
니트로소아민은 화학물질이 화학반응 과정중에 분해되어 2차 아민형태로 공기중의 질소산화물(NOx) 가스, 질산, 나이트라이트 등과 같은 질화제(nitrosating agent)와 반응하여 생성된 인체에 유해한 발암물질인 N-니트로소 조성물(N-nitroso compound)를 말하는 것으로, 니트로소아민의 발생은 타이어산업 뿐만 아니라, 식품산업을 포함한 다른 산업분야에서 발생량이 더욱 많은 실정이나 타이어산업이 주목받는 이유는 해당산업의 조직력과 영향력이 막강하여 다른 산업에 영향을 줄 수 있기 때문에 특별히 관리한다는 Spot-Light Theory에 근거하고 있다.Nitrosoamines are carcinogens that are harmful to the human body formed by chemicals that break down during chemical reactions and react with nitrifying agents such as nitric oxide, nitric acid and nitrite in the air in the form of secondary amines. N-nitroso compound (N-nitroso compound), the occurrence of nitrosoamine is not only in the tire industry, but also in the other industries, including the food industry, the occurrence of more attention, but the tire industry is attracting attention because of It is based on the Spot-Light Theory, which specifically manages it because it is powerful and can influence other industries.
이들 니트로소아민에 대한 규제는 전세계적으로 볼 때, 아직까지는 독일 노동청의 위험물질에 대한 기술적 규범으로만 관리가 되고 있는데, 현재 독일에서도 환경청의 환결규제가 아닌 노동청의 작업장에 대한 규제내용으로만 적용이 되고 있으나, 향후 2000년 이후에는 직접적인 규제 가능성이 높아 이들에 대한 대책 마련이 시급한 실정이다.Globally, regulations on these nitrosoamines are still managed by the German Labor Administration as technical norms for dangerous substances. Currently in Germany, only the Ministry of Labor's workplaces, not the Environmental Protection Agency's regulations, However, since 2000, the possibility of direct regulation is high, and it is urgent to prepare countermeasures for them.
이에 본 발명자들은 상기와 같은 문제점을 해결하기 위한 연구를 수행한 결과, 신재료를 사용한 가교시스템을 도입함으로써 발암물질인 니트로소아민의 발생을 방지하고 기존의 가교시스템이 가지는 고무조성물의 물성과 동등 이상의 수준을 유지할 수 있는 새로운 고무조성물을 제조할 수 있음을 알아내고 본 발명을 완성하였다.Accordingly, the present inventors have conducted research to solve the above problems, and as a result, by introducing a crosslinking system using a new material to prevent the generation of nitrosoamine, a carcinogen, and more than the physical properties of the rubber composition of the existing crosslinking system The present invention has been accomplished by finding that a new rubber composition can be produced that can maintain levels.
따라서, 본 발명의 목적은 안정적인 가교시스템을 가지고 있으나 물질의 분자구조내에 2차아민의 형태를 가지고 있어서 발암물질인 니트로소아민을 형성하여 환경유해요소로 작용하는 기존의 고무조성물을 대체할 수 있는 새로운 고무조성물을 제공함에 있다.Accordingly, an object of the present invention is to have a stable crosslinking system, but in the form of secondary amines in the molecular structure of the material to form a carcinogen nitrosoamine can replace the existing rubber composition acting as an environmentally harmful element To provide a new rubber composition.
본 발명은 천연고무를 원료고무로 하는 타이어용 고무조성물에 있어서, 천연고무 100 중량부에 대하여 가교제로 1,6-비스(N,N 디벤질티오카바밀디티오)-헥산을 0.2∼4.0 중량부 함유하는 타이어용 고무조성물 임을 특징으로 한다.In the rubber composition for tires made of natural rubber as raw material rubber, 0.2 to 4.0 weight of 1,6-bis (N, N dibenzylthiocarbamyldithio) -hexane as a crosslinking agent based on 100 parts by weight of natural rubber It is characterized in that the rubber composition for the tire containing minor.
기존의 천연고무로 블렌드된 고무조성물에 일반적으로 사용되고 있는 촉진제의 구조는 아래의 구조식과 같은데, 이들 촉진제는 다른 촉진제와 비교할 때 높은 스코치안정성 등 안정적인 가교형태를 가지나 발암물질인 니트로소아민을 발생시키는 문제점을 안고 있기 때문에, 본 발명에서는 가교반응 촉진제로 MOR과 가교제로 Sulfasan-R 대신에 새로운 재료인 1,6-비스(N,N디벤질티오카바밀디티오)-헥산(1,6-bis-(N,N dibenzylthiocarbamoyldithio-hexane ; 이하, KA-9188)을 천연고무 100 중량부에 대하여 0.2∼4.0 중량부 사용하는데 만일 0.2 중량부 미만 사용하면 분산 상태에 크게 영향을 받아 물성 개선 효과가 미미하고, 4.0 중량부 초과 사용하면 물성 개선 효과에 별다른 변화가 없이 비용만 증가하게 되어 바람직 하지 않다.The structure of accelerators generally used in rubber compositions blended with conventional natural rubbers is as shown in the following structural formula.These accelerators have stable crosslinking forms such as high scorch stability compared to other accelerators, but they produce nitrosoamine, a carcinogen. In the present invention, a new material 1,6-bis (N, Ndibenzylthiocarbamyldithio) -hexane (1,6-bis instead of MOR as a crosslinking accelerator and Sulfasan-R as a crosslinking agent is present in the present invention. -(N, N dibenzylthiocarbamoyldithio-hexane; hereinafter KA-9188) is used in an amount of 0.2 to 4.0 parts by weight based on 100 parts by weight of natural rubber. In case of using more than 4.0 parts by weight, it is not preferable to increase the cost without any change in the property improvement effect.
또한, 본 발명에 사용된 가황제는 고분자황(insoluble sulfur)을 천연고무 100 중량부에 대하여 0.5∼5.0 중량부 사용하는데 만일 0.5 중량부 미만 사용하면 물성 개선 효과가 미미하고, 5.0 중량부 초과 사용하면 물성 개선 효과에 별다른 변화가 없이 비용만 증가하게 되어 바람직 하지 않다.In addition, the vulcanizing agent used in the present invention uses 0.5 to 5.0 parts by weight of insoluble sulfur with respect to 100 parts by weight of natural rubber. If less than 0.5 parts by weight is used, the improvement of physical properties is insignificant, and more than 5.0 parts by weight is used. This is undesirable because it only increases the cost without any change in the physical properties improvement effect.

고무조성물의 물성을 알아보기 위하여 실시예 1 내지 실시예 4 및 비교예에 의해 제조된 고무조성물의 무늬점도(Mooney Viscosity), 레오시험(Rheo Test), 초기 및 노화후의 장력시험(Tensile Test) 및 일정크기와 형태를 가진 고무시편을 빠르게 진동하는 압축응력을 가해 진동응력에 따른 고무 내부의 온도상승을 측정하는 시험방법 즉, 가류고무 시편에 동적압축 변형을 가하여 발열속도를 비교하는 시험방법인 H.B.U.를 ASTM에 규정된 방법에 의하여 시험한 결과를 아래의 표 2에 나타내었다.In order to determine the physical properties of the rubber composition of the rubber composition prepared by Examples 1 to 4 and Comparative Examples (Mooney Viscosity), Leo Test (Rheo Test), initial and post-aging Tensile Test (Tensile Test) and HBU, a test method for measuring the temperature rise inside the rubber according to the vibration stress by applying a compressive stress that vibrates a rubber specimen having a certain size and shape, that is, a test method for comparing the heating rate by applying dynamic compression deformation to the vulcanized rubber specimen. The results of the test by the method specified in ASTM are shown in Table 2 below.
표 2. 고무조성물의 물성시험 결과Table 2. Property test results of rubber composition
본 발명에 의한 타이어용 고무조성물은 분자구조 내에 2차아민 구조를 갖지 않는 물질을 함유하고 있기 때문에, 종래의 고무조성물의 물성과 비교하여 동등한 수준 이상의 물성을 유지하면서도, 특히 고무조성물의 노화물성이 현저하게 개선되면서도 발암물질인 니트로소아민을 생성하지 않는 환경친화적이라는 장점이 있다.Since the rubber composition for tires according to the present invention contains a substance having no secondary amine structure in its molecular structure, the rubber composition of the rubber composition is particularly maintained while maintaining the properties of equivalent or higher properties as compared with those of conventional rubber compositions. Significantly improved, but does not produce a carcinogenic nitrosoamine has the advantage of being environmentally friendly.
또한, 보다 높은 스코치 안정성을 갖으며 가류속도(cure rate)가 빨라지게 됨에 따라 본 발명에 의한 고무조성물을 타이어에 적용시 높은 공정안정성을 유지시킬 수 있는 장점이 있다.In addition, there is an advantage that can maintain a high process stability when the rubber composition according to the present invention is applied to the tire as it has a higher scorch stability and the cure rate is faster.
